WASHING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 581,509, dated April27, 1897.

Application filed February 3, 1897. Serial No. 621,771. (No model.)

To ctZZ whom it nuty concern:

Be it known that I, CONRAD DIETZ, a citizen of the United States,residing at West Covington, in the county of Kenton and State ofKentucky, have invented a new and useful Improvement inWashing-Machines,of which the following is a specification.

My invention relates to novel means for uniting the connecting-rod tothe crank of a lo washing-machine.

, The object of my invention is to provide a simple, durable, andinexpensive connectingrod which may be detachably united to the crank,and easily and quickly put on and taken off.

My invention consists in the construction of the connecting-rod andpitman, in their relative arrangement with each other and with thecrank, and in the parts and combi- 2o nation of parts shown in thedrawings and hereinafter more fully described, and pointed out in theclaim. 7

In the drawings, Figure 1 is a vertical longitudinal section through awashing machine 2 5 embodying my invention, showing the arrangement ofthe operative parts of the machine and the relative position of myinvention to those parts when applied thereto. Fig. 2 is a detailperspective View of a portion of the pitman and connecting-rod, showingtheir relative arrangement when the pitman is pivotally secured upon thecrank and the hook of the connecting-rod inserted in the recess of thepitman and over and partly 3 5 around the crank. Fig. 3 is a detail sideview of the separable end of the pitman adapted to take over the crank,showing its parts bolted together and a recess adapted to receive thehook end of the connecting-rod. Fig. 4 is a detail side view of theupper end of the connecting-rod adapted to take into the recess in thepitman and over and partly around the crank. Fig. 5 is a side elevationof the crank and portions of its shaft with the 5 pitman mountedthereon, the same having its end broken away to show the position of theconnecting-rod upon the crank and the manner of holding it in engagementthere- I with while the machine is in its normal and operative position.

I prefer to construct the casing A and the cover A of thewashing-machine substantially of the form shown in Fig. 1, theclothesreceptacle B being pivotally and detachably mounted within thecasing by means of suitable bearings and journals. The dasher O ispivotally mounted in suitable bearings in the cover and is connected toone end of the pitman D by means of an arm 0, which arm extends upthrough an elongated opening in the cover, the other end of the pitmanbeing separable to permit of its being mounted on the crank E of shaftF, which latter is suitably mounted upon the machine andis operated by adrive-wheel G, all substantially as shown.

The connecting-rod H is detachablyconnected at its lower end to theclothes-receptacle by means of plate I, having a lateral stud itoreceive the collar of the connectingrod and a horn 1', extending partlyaround the free end of the stud to retain said rod from accidentaldisengagement with the stud.

The upper end of the connecting-rod is recessed to form a hook it andshoulder h, adapted to take into the recess cl in the pitman and partlyover and around the wrist e of the crank, thus uniting theconnecting-rod to the crank and dispensing with intermediate connectingmechanism by which to make the rod detachable. It will be seen that bythis construction and arrangement the connecting-rod hooks over thecrank and is held in engagement therewith by the recessed pitman and web6 of the crank, as clearly shown in Fig. 5.

To unite the connecting-rod H to the crank E, disconnect pitman D andarm 0 and swing the pitman upwardly until the hook h is allowed to enterrecess d and take over and partly around wrist 6. Then draw the pitmandown and reconnect it to arm 0. WVhen the parts have been connected, asshown in Fig. 1, the dasher and receptacle may bevibrated in oppositedirections simultaneously by turning the drive-Wheel on the crank- 5shaft. To disconnect the connecting-rod H from the crank, elevate thepitman until the shoulder 61 on pitman D bears against shoulder h on theconnecting-rod H and forces hook h off of the crank.
